VizieR Online Data Catalog: Small Kepler planets radial velocities (Marcy+, 2014)
Abstract
Here we report measured masses, radii, and densities (or upper limits on those values) for 42 transiting planet candidates contained within 22 bright Kepler Objects of Interest (KOIs) from Batalha et al. (2013, Cat. J/ApJS/204/24). We carried out multiple Doppler-shift measurements of the host stars using the Keck 1 telescope. From the spectroscopy and Doppler measurements, we compute self-consistent measurements of stellar and planet radii, employing either stellar structure models or asteroseismology measurements from the Kepler photometry. We also search for (and report) 7 additional non-transiting planets revealed by the precise radial velocities (RVs), for a total of 49 planets.
We carried out "reconnaissance" high-resolution spectroscopy on ~1000 KOIs with spectral resolution, R~50000, and S/N=20-100 per pixel. The dual goals were searching for false positives and refining the stellar parameters. We obtained one or two such reconnaissance spectra using one of four facilities: the McDonald Observatory 2.7m, the Tillinghast 1.5m on Mt. Hopkins, the Lick Observatory 3m, and the 2.6m Nordic Optical Telescope. Speckle imaging of each of the selected 22 KOIs was obtained using the two-color DSSI speckle camera at the WIYN 3.5m telescope on Kitt Peak. All 22 KOIs were observed with the Keck NIRC2-AO system.
